I've grown ginger this year on the kitchen windowsill - a inch of root has yielded another three. I've got a Turmeric plant as well which has grown so strongly it has mis-shaped its pot, but I don't know what to do with it? It is a much more attractive shaped plant than the ginger.
I'm trying it again with some turmeric this time! I planted in March, keep inside until May then into the greenhouse (attach to house) probably until October then back inside in front of south facing window until December. André I have no idea if the shoot are edible. If the old shoots are brown and dry i would cut it.
I would guess so ! If you have a south facing window with good sun access (no trees or building) it should be ok. From my observation ginger seem to love warm temperature( lots of growth). One thing is for sure it's slow about 9 months from seed to plate !
